I'd agree that the 1A would be a tad light (for my tastes) in an '06. The No.1's I've fired with 22" barrels include 7x57, 9.3x74 and 45-70. The 7x57 is mild, though the heavier kickers are rather 'lively' due to the short overall rifle length. I do have a 1A in 7x57 (22") and a 1S in 300 H&H (26"), though am unsure on actual weights. I do believe the 26" 1S is close to 8 lbs, and would expect the 1A to be closer to 7 lbs. I've always felt a 24" barrel would be ideal on a No. 1 and the '06 in that configuration sounds perfect.
